[OE-core] [PATCH] oe-selftest: Improved --list-classes when determining test names

[Daniel Istrate]

--list-classes does a weak validation when determining test names:
(if method.startswith("test_") which could report any class attribute
that starts with 'test_' as a valid test case.

This fix checks that the class attribute that starts with 'test_'
is also callable (is a method).

Fix for [YOCTO #8862]
